Dual-pipe damper under cyclic loading Abaqus

Product Overview

In this example, we intend to simulate the dual-pipe damper under cyclic loading in the Abaqus software.

In the right picture, the laboratory model and in the left picture, the sample having been simulated in the Abaqus software can be observed.

Test Setup

The test setup used for the experimental study can be observed in the following picture.

Cyclic Loading

In this problem, a cyclic loading is applied to the model, and following that, its hysteresis diagram is drawn.

The loading history is defined using the corresponding amplitude data in Abaqus to reproduce the cyclic loading protocol.

Hysteresis Diagram

After applying the cyclic loading, the Force-Displacement hysteresis diagram is obtained from the Abaqus results.

In this picture, the Force-Displacement hysteresis diagram obtained from the Abaqus software is compared with the experimental results.

Comparison of Abaqus and Experimental Results

The numerical results obtained from the Abaqus software are compared with the experimental results reported in the reference study.

As you can observe, the Abaqus results show good agreement with the experimental results.

Deformation of the Dual-Pipe Damper

In this picture, the deformation of the dual-pipe damper under cyclic loading can be observed.

Validation

This project has been validated, which means that the results obtained from the Abaqus software are similar to the results reported in the article.

In other words, this project is based on the reference article and the numerical model has been developed to reproduce the experimental behavior of the dual-pipe damper under cyclic loading.
